Key Points

  • New large-tonnage REE targets discovered at company’s 100% owned Gascoyne acreage
  • All targets modelled to be vertical cylindrical bodies
  • The largest is the Mt Weld Plug, some 3-4km in diameter

Lanthanein Resources (ASX:LNR), formerly Frontier Resources, has identified new rare earth element (REE) targets for exploration at its Gascoyne REE project. 

Multiple intrusive targets have been discovered, including a large vertical cylindrical body 3-4km in diameter called the Mount Weld Plug. 

Three other intrusive targets have been modelled as vertical cylindrical bodies 2-4km in diameter within the Lyons Block, perceived to extend below 2km depth. 

The intrusive Carbonatite targets represent a new large-tonnage REE target for the company.

Locally experienced researcher assisting exploration

Independent consultant Franco Pirajno managed all modelling activities based on the data. 

Pirajno is to stay on board for the company’s upcoming maiden drilling program to further interpret results collected. 

Lanthanein is confident in Franco’s previous experience within the area. The same individual has worked on the Mt Weld and Gifford Creek REE Carbonatites, with similar geological traits to new targets identified by the company. 

Recent third-party drill results drive optimism 

The company also notes recent drilling by Lynas Rare Earth Limited (ASX:LYC) which intercepted REE mineralisation along a 1,020m core sample.

Lynas’ results showed an average grade of 2.22% Rare Earth Oxides (REOs) per tonne. 

Shallow anomalous grades included 13.67% REO along a 20m section. 

Three targets on the cards for exploration 

Lanthanein notes target LI01 is thought to be a 4.3km wide and 1km deep formation which emanates from a larger magnetic intrusive body at depth. 

Anomalous thorium zones occur within LI01, a promising sign for REE exploration; these zones have been made drill targets for REE ironstone by the company’s geology team. 

Target LI02 is a circular body of 2.8km diameter emanating from a deeper source similar to that encountered in LI01. 

The third target, LI03, is described as having “amphitheatre” shaped dimensions and occurs adjacent to numerous thorium-containing ironstones. 

Heritage survey delay 

However, the company also notes the presence of covid cases on site has led to a delay in the acquisition of heritage avoidance surveys. 

The survey team has been temporarily suspended while positive-testing members recover. Heritage surveys are expected to re-commence later this month.
